1 Claim. l

An object of the'invention resides in the provision of a windowconstruction which includes; a frame and vertical slidable sashes inVsuch manner that the sashes and frame may be adjusted' so that they willbe in an efficient operativeV alignment with each other to insure theproper opera'- tion of the sashes as they are raised and lowered, tocenter the sashes when they are'elo'sed 'with the meeting rails of thesashes in alignment with each other.

It is a further object of the invention' to provide for the sealing ofthe spaces between the sashes and the window frame and between themeeting rails of the sashes against'weather leakage when the sashes arein their closed positions.

A still further object of the invention resides in the provision in sucha device as above described of means which will permit the refloatingsash movements as they are raised or lowered.

Further it is an'object of the inventionto provide the sashes withcooperative window locking and aligning means which, when the sashes aremoved to their closed positions, Will align the' sashes with each otherboth vertically and horizontally and in relation to the Window frame.

With these and other objects in view, such` as will appear as the`description of the' invention progresses, the invention resides in'thecombination and arrange-ment of parts illustrated in the drawing,described in the specification and recited in the claim.

In the drawing:

Figure 1 is a horizontal sectional view of a fragment of a windowconstruction illustrating an embodiment of the invention;

Figure V2 is a fragmentary elevational view showing the sash centeringand locking device;

Figure 3 is a vertical sectional view 25on`line 3 3 of Figure 1; and

Figure 4 is a verticalv sectional viewy through the sashes and frameshowing the relation of the same and the weather stripping arrangement.

Referring, now, to the structure illustrated in the drawing, andparticularly to Figures 1 and 3^, a vertical frame member of a metallicwindow frame is illustrated.l This includes (as'does also 2 notch in theupper rail of the lower sash being shown inFigures` 1 and 3 at I8.

These blocks I1 are secured to the parting bead I6 by countersunk screwsIl and are prevented from having rotative movement by lugsj I8' thatengage with complemental openings in the parting bead. These blocksserve to prevent air leakage through the said notches in the upper andlower sashes and assist in properly locating the sashes in the framewhen the sashes are inclosed positions. A

The side rails of the upper and lower sashes carry resilient metallicweather stripping I6', as

illustrated in Figure l, which; cooperates with self l the space betweenthe upper rail of the upper sash and the header. The upper rail I5 ofthe lower sash carries a resilient weather stripping I2 which cooperateswith the lower rail of the upper sash to seal the space between thesemeeting rails.

A combined anchor and adjuster is associated with each vertical jambofthe window frame,

one of the same being illustrated in Figures 1 and 3.

In thisY construction an anchor plate I9 is provided, which plate issecured to the window opening framing 20 by suitablemeans such as aYscrew 2 I, and is attached to the adjacent window frame jamb by ears 22and 23, which embrace a flange 2li on the jamb and by ear 25 whichcooperates with a portion'26 of the anchor plate to embrace anotherflange 21 onY the jamb.

AnV adjuster isy mounted on the anchor plate I9. This Yadjustercomprises a screw member 28'that is adjustably engaged in a threadedopen/ing 29 inthe plate I9. A bearing head 30 is rigid with the screwmember 28 and has a bearing face SI that is vadapted to engage and footagainst the adjacent face of the window opening framing 20 so that. whenthe screw is adjusted-the adjacent window frame jamb-may be adjustedbetween its ends where'it meets vthe header andsill to force thejambinwardly and torelieve it of -any outward bowing that it may possessand to, also, move the ller block I1 inwardly into proper position tosubstantially fill the spaces I8 heretofore referred to.

This adjustment of the screw 28 may be accomplished by rotating the head30 by means of a tool, such as a screw driver, that may be engaged innotches 32 in the periphery of the head 30.

The lower rail of the upper sash I5 is provided with a plate 33 which issecured thereto and which carries a fastener hook member 34 which opensdownwardly. A pair of spaced projections 35 protrudes from the face ofthe plate 33 inwardly for a purpose which will be described.

The upper rail of the lower sash I4 has a plate 36 rigidly attachedthereto, and from this plate cam members 31, having cam faces 38, extendoutwardly and downwardly. These cam members 31 are so located that, whenthe sashes are closed, they will extend between the projections 35, andthey are so spaced that the cam faces 38 are capable of engaging theprojections 35 to align and position the sashes with respect to eachother.

This plate 3S carries also a cam lock 39 having a cam member 40 forengagement with the hook member 34 to lock the sashes together, whichengagement may be accomplished through a iinger piece 4 I.

With this construction it is possible to so adjust the window framejambs and filler blocks I1 as well as the sashes that a propercooperative relationship between these elements will be established toproduce a properly operating and functioning window construction.

It will be understood that, when the sashes are closed, there should bea relatively weather tight joint between the side rails of the sashesand the jambs of the window frame which of course requires a properrelative positioning of the usual weather stripping and also thesubstantial lling of the notches, such as I8, in the meeting rails ofthe sashes, by the blocks I1. Moreover, the sashes should be sopositioned laterally with relation to each other that the full benefitof the proper functioning of the weather stripping of both sashes willbe attained.

The adjuster, the sash centering device and the blocks heretoforedescribed cooperate with each other to attain the above results andadvantages.

When the window frame jambs are bowed outwardly, or require inwardadjustment, this may be accomplished by the adjuster heretoforedescribed. Such adjustment will properly correlate the jamb members withthe vertical rails of the sashes and the cooperating weather strippingbetween said rails and window frame. Furthermore, such adjustment willproperly position the blocks I1 so that, when the sashes `are closed,they effectively will fill the notches in the meeting rails of thesashes sufliciently to form weather seals at these points.

However, to perfect the operation of the sashes and the weather sealingof the window, one or the other of the cam faces 38 on the cams 31 willengage the adjacent projection 35 as the sashes are being closed, withthe result that the sashes will be given relative lateral movement toproperly adjust each with respect to the other and with respect to thewindow frame and filler blocks.

Moreover, the filler blocks I1 are provided, as illustrated in Figure 3,with cam faces II' and I2" so that when the lower sash is lowered from araised position the edge of the notch I8 therein will engage the camface II' in case the sash is closer to one frame jamb than to the otherand upon further movement will move the sash laterally into its properposition. When the upper sash is raised from a lowered position the camface I2" of the block I1 will be engaged by the edge of the notchcorresponding with the notch in the lower rail of the upper sash andwill coact with the upper sash in the manner just described inconnection with the movement of the lower sash.

Thus it will be seen that when the upper and lower sashes are moved fromopen positions to closed positions after the blocks I1 have beenproperly positioned by means of the adjusters heretofore described, thesaid blocks will coact with the meeting rails of the sashes to assist Ain centering the sashes in the frame. As the cam members 31 engage theprojections 35 the sashes will be horizontally and vertically alignedwith each other and when the cam 40 is engaged with the hook member 34the meeting rails-of the sashes will be drawn together and through theweather stripping I2 will seal the joint between these rails. Moreover,this cam action will force the upper weather stripping I4' intoengagement with the head of the frame and at the same time will forcethe lower weather stripping I3 into engagement with the sill member ofthe frame. Additionally, in drawing the meeting rails of the sashestogether this cam member 43 will also contact the side rails of thesashes with the self lubricating inserts I5', at which time theresiliency of the weather stripping I6 will maintain a seal between thejamb of the frame and the side rails of the sashes.

Thus the blocks, the window locking member, the adjuster and the weatherstripping will cooperate to properly position the jambs of the frame,align the sashes with each other and seal the spaces between the sashesand the frame and between the meeting rails of the sashes, with theresult that the sashes may easily be raised `and lowered and when inclosed position will be effectively sealed and locked against weatherinltration into the room. f

In window frames which are constructed of metal such as relatively thinextruded aluminum, before the Vframes are set in the building the jambsofttimes bow outwardly between their ends so that the frame is no longera true rectangle. It is, therefore, desirable to provide means foradjusting the jambs so that the frame will be restored to its originalcondition, i. e., to a rectangular form, for otherwise the sashes willnot properly slide within the channels.

In this type of window where weather stripping is provided for theupper, lower, vertical and meeting rails of the sashes it is notpossible to provide this weather stripping at the ends of the horizontalrails where they align with thev parting beads and so it has been thepractice to notch these ends as at I8 in Figure 1 and provide fillerblocks such as I1 for preventing the infiltration of air through thewindow at these points when the sashes are closed. However, it isnecessary to provide some space between the faces of the filler blocksI1 and the adjacent edges of the meeting rails of the sashes so thatthere will not be a drag between the two pieces of aluminum.

In order that the two sashes may have their side vertical rails alignedwith each other as they are being closed so that they will both closelyalign with the adjacent faces of theblocks I1 the meeting rails of thesashes are provided with the cooperating cams 35 `and 31, thelatterhaving the cam faces 38 which ride upon the cam proj ections 35 asthe two rails are being brought into alignment with each other with theresult that the sashes will be adjusted laterally to align their siderails vertically and properly space them in respect of the ller blocksI1 and the jambs. In this way the sides of the sashes where they engagewith the jambs will be sealed against air infiltration. Then' when thecam shaped lock 39 is engaged with the hook member 34 the sashes will bemoved apart vertically to seal the upper and lower rails within theheader and sill and at the same time because of the eccentric camportion 40 the meeting rails will be drawn together to seal them againstthe weather strip that is interposed therebetween.

Thus with this adjustment of the jamb members the cooperation of the camelements 35 and 31 and the cooperation of the lock elements 34 and 39,the top and bottom and the sides of the sashes and the meeting rails aresealed. In order to get this seal it is of course necessary when thejambs are sprung outwardly to adjust them inwardly for otherwise therewould be no proper seal at the ller blocks I1.

While a particular construction has been illustrated and described, thishas been for the purpose of disclosing an embodiment of the inventionand it is to be understood that changes in details of construction maybe made without departing from the spirit of the invention or exceedingthe intent and scope of the claim.

What is claimed is:

In a metallic window construction which comprises a frame havingvertical jambs with sashreceiving channels therein between which isarranged a parting bead and a pair of vertically slidable sash membersmounted for movement in said channels, the upper rail of the lower ofwhich sashes and the lower rail of the upper of which sashes areprovided with complementa] openings adjacent said parting bead, theimprovement which includes a filler block carried by said parting beadand aligned with the upper rail of said lower sash and the lower rail ofsaid upper sash when the sashes are closed and located in said recessesand substantially filling the same, a pair of downwardly converging cammembers carried by the lower rail of the upper sash, a pair ofprojections on the upper rail of the lower sash having their inner facesseparated a distance substantially equal to the distance between saidcams at their greatest point of divergence and between which said camsare adapted to move when the lower rail of the upper sash and the upperrail of the lower sash are brought into alignment, and a screw devicefor adjusting the position of said ller block transversely of the windowand in respect of the recesses in the rails thereof whereby inoperation, when the sashes are closed, they will be aligned into asubstantially continuous rectangular form and the recesses in the rails.

thereof will be substantially filled by the iiller blocks.
